Donald Trump had an opportunity to apologize for stoking conspiracy theories about Barack Obama’s birth certificate on Friday… and he declined to do so.

In fact, while acknowledging the fact that Obama was really born in the United States, Trump told a new lie by claiming that it was Hillary Clinton who first raised the issue of Obama’s birth certificate back in 2008.

The entire Congressional Black Caucus held a press conference on Friday afternoon in which they tore Trump’s birther remarks to pieces and say it was unacceptable that such a bigoted person should ever become president.

Rep. Jim Clyburn (D-SC) said that while there’s nothing new about the use of racial dog whistles in American politics, what Trump is promoting is far louder and more insidious than any politician in recent memory.

“One of the things that we are all used to in this business is dog whistles,” he said. “But the thing that we’re not used to… are the howls of wolves. These are howls, these are not whistles. These are in-your-face kinds of efforts on the part of one man… in order to heap indignities on the President of the United States.”

Rep. Sheila Jackson Lee (D-TX) was even more blunt about Trump.

“He has lived a life of bigotry,” she said. “If you view America as a land of value and equality and justice, this man cannot be elected. We as African Americans have had enough. He has debased this election, but more importantly, he has disgraced himself in his lack of respect for the President of the United States of America.”

Rep. Gregory Meeks (D-NY) called out Trump for being a shameless liar — and not just about President Obama’s birth certificate.

“This is not the first time he has lied — he continues to lie,” Meeks fumed. “He’s lied and he’s divided this country enough. He lied about Muslims, saying he saw thousands of them [celebrating] when the World Trade Center went down. He’s lied about Mexicans, he’s lied about women, and members of the Congressional Black Caucus are not going to take it anymore.”
